[File:Celts in Europe.png|300px|thumb|right|Diachronic distribution of Celtic peoples:
]] This is a list of Celtic tribes, listed in order of the Roman province (after Roman conquest) or the general area in which they lived. This geographical distribution of Celtic tribes does not imply that tribes that lived in the same general geographical area were more related. Some tribes' or tribal confederation's names are listed under more than one region because they dwelt in several of them.
